Keep in mind that course updates that you make might take longer to
appear in the edX mobile apps than on the edX site. In particular, newly
published content can take up to an hour to update on the Android app.

Learners can search course text in HTML components and video transcripts by using the Search box at the top of
the Course page.

Before learners can search your course, Studio must index the content. Studio
indexes all new course content automatically when you publish the content.

If necessary, you can manually reindex all of the content in your course at
any time. Typically, you would only manually reindex your course content if
learners see unexpected search results. To reindex your course content,
select Reindex Content at the top of the Course Outline page.
Reindexing usually takes less than 30 seconds.
